The www builds include disableLegacyContext as a dynamic flag, so we
should be running the tests in that mode, too. Previously we were
overriding the flag during the test run. This strategy usually doesn't
work because the flags get compiled out in the final build, but we
happen to not test www in build mode, only source.
To get of this hacky override, I added a test gate to every test that
uses legacy context. When we eventually remove legacy context from the
codebase, this should make it slightly easier to find which tests are
affected. And removes one more hack from our hack-ridden test config.
Given that sometimes www has features enabled that aren't on in other
builds, we might want to consider testing its build artifacts in CI,
rather than just source. That would have forced this cleanup to happen
sooner. Currently we only test the public builds in CI.
## Summary
- yarn.lock diff +-6249, **small pr**
- use jest-environment-jsdom by default
- uncaught error from jsdom is an error object instead of strings
- abortSignal.reason is read-only in jsdom and node,

The old version of prettier we were using didn't support the Flow syntax
to access properties in a type using `SomeType['prop']`. This updates
`prettier` and `rollup-plugin-prettier` to the latest versions.
I added the prettier config `arrowParens: "avoid"` to reduce the diff
size as the default has changed in Prettier 2.0. The largest amount of
changes comes from function expressions now having a space. This doesn't
have an option to preserve the old behavior, so we have to update this.

I don't think "array or iterator" is adding anything, and it may well be confusing, especially since this is one of the first and most common warnings that devs see.
